Soil Stabilization with Chemicals

This bulletin is the second in a series of compilations of reports on completed research done for the Iowa Highway Research Board Project HR-1, "The Loess and Glacial Till Materials of Iowa; an Investigation of Their Physical and Chemical Properties and Techniques for Processing Them to Increase Their All-Weather Stability for Road Construction." The research, started in 1950, was done by the Iowa Engineering Experiment Station under its project 283-S. The project was supported by funds from the Iowa Highway Research Board of the Iowa State Highway Commission. In Iowa the abundance and wide distribution of loess and glacial till materials makes them the logical ones with which to start working. The principal objectives of the project may be summed up as follows: 1. To determine by means of both field and laboratory studies the areal and stratigraphic variation in the physical and chemical properties of the loess and glacial till materials of Iowa; 2. To develop new equipment and methods for evaluating physical and chemical properties of soil where needed; 3, To correlate fundamental soil properties with the performance of soils in the highway structure; 4. To develop a scientific approach to the problem of soil stabilization based on the relationships between the properties of the soils and those of the admixtures; and 5. To determine the manner in which the loess and glacial till materials of Iowa can be processed for optimum performance as highway embankments, subgrades, base courses, and surface courses. Many of the papers in this bulletin were prepared originally as graduate theses required by the Department of Civil Engineering for master or doctoral degrees at Iowa State University. Each was then rewritten with the assistance of other project workers and was submitted to the Iowa Highway Research Board as a report on a phase of the research. This explains the several authors for each paper. The research work was all done under Dr. D. T. Davidson as project leader in charge. Practically all the papers herein have been published previously. The title page for each manuscript identifies all authors and gives the place and date of first publication. No attempt has been made to revise, update, and change the data; hence some contradictions are evident. The facts and conclusions presented are those of the authors at the time the manuscript was submitted. Much of the repetition of material has been eliminated, and the papers have been arranged by subject matter.
